PHILIP NELSON, OF WATROUS, NEW MEXICO.

NUT-SPLITTER.

Specification of Letters Patent.

Application filed May 11, 1912. Serial No. 696,693.

Patented Sept. 10, 1912.

To all whom it may concern:

Be it known that I, PHILIP NnLsoN, a citizen of the United States,residing at Watrous, in the county of Mora and State of New Mexico, haveinvented certain new and useful Improvements in Nut-Splitters,

of which the following is a specification,

Another object of the invention is to provide a device of this characterwhich will possess advantages in points of efliciency and durability, isinexpensive to manufacture and at the same time is simple inconstruction and operation.

With the above and other objects in view the invention consists in thenovel features of construction and the combination and arrangement ofparts hereinafter more fully described, pointed out in the claims, and

shown in the accompanying drawings, in

which- Figure 1 is an elevation of my improved nut splitter. Fig. 2 is asectional view on the line 22 of Fig. 1. Fig. 3 is a sectional view onthe line 33 of Fig. 1. Fig. 4, is a sectional View on the line 44, ofFig. 1. Fig. 5 is a sectional view on the line 55 of Fig. 1.

Referring more particularly to'the drawings, 1 indicates the casingwhich comprises the body plate 2 which is provided at one end with atransverse enlarged portion 3, and is further provided with alongitudinal slot 4 having an enlarged central portion 5. Mounted in thelower end of the slot 4 is the stationary cutting member 6, which isprovided at one end with a hollow ground cutting blade 7. Outwardlyextending flanges 8 are formed upon the longitudinal edges of the member6 and adapted to rest upon the base plate to prevent the removal of thecutting member. A guide plate 9 is mounted upon the lower end of thebody plate 1 and is held securely in position by means of the bolts 10,said guide plate being provided with a longitudinal recess 11, adaptedto receive the flanges 8 formed on the cutting member 6 so that thecutting member will be securely held against any relative lateralmovement.

A rack bar 12 is slidably mounted upon the base plate 1 and is providedwith an outwardly extending lug 13 upon one side thereof which isdisposed in the slot 4 to guide the rackan d' at the same time hold therack against lateral movement. A longitudinal recess let is formed inthe lower end of the rack 12 and a stud 15 is arranged in said recesshaving its outer end flush with the side edges of the rack bar. Areciprocating cutter member 16 is provided having flanges 17 formed uponits longitudinal edges and provided at one end with an opening 18 toreceive the stud 15 upon the rack bar. Thus it will be seen that thecutter member 16 is slidably mounted in the upper end of the slot a soas to prevent any lateral movement. The cutting member 16 is provided atits lower end with the hollow ground cutting edge 19 which is arrangedin alinement with the cutting edge 7 on the member 6.

The rack bar 12 is provided upon its side edes with a plurality of teeth20 which are adapted to be engaged by oppositely dissubstantially thesame form as the body plate and is provided with the openings 26,adapted to receive the ends of the bolts 10 and 23 so that the plate'25may be securely held by means of the nuts 27.

From the above description it will be readily seen that the operatingparts are arranged between the body plate 1 and the cover plate 25. Inreciprocating the bar 12 which carries the cutter member 16, the handles22 are moved outwardly and inwardly in the arc of a circle. Thus it willbe seen that a nut placed between the cutting edges 7 and 19 will bequickly and readily split in two by actuating the handles 22 to removethe nut from the bolt. It will be readily seen that the cutting edgesproject beyond the outer face of the base plate as shown at 28 so that anut which is partly embedded in the wood can be readily grasped andsplit more quickly than if the cutting edges were flush with the outerface of the plate 1.

In using my improved nut splitter the nut is first arranged in theenlarged portion 5 of the slot -it so that it will be directly betweenthe cutting edges 7 and 19, the handles 22 are then brought togetherwhich will force the cutting edge 19 downward into one of thelongitudinal edges of the nut and at the same time it will force theother side of the nut downwardly upon the cutting edge 7 so that thecutting edge 7 will split that side of the nut.

From the above description taken in con nection with the drawings itwill be readily seen that I have provided a nut splitter whereby a nutcan be quickly and easily cut from a bolt without destroying the bolt inany manner, and that I have also provided a nut splitting tool which isextremely simple and durable and that can be manufactured at a very lowcost.

While I have shown and described the preferred form of my invention itwill be obvious that various changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope thereof.

What I claim is 1. In a device of the character described, thecombination of a base plate having at one end a transversely extendingenlarged portion, said plate being provided with a longitudinal recesshaving a central enlarged portion, a cutting member arranged in thelower end of the recess, flanges formed upon the longitudinal edges ofsaid cutting memher and resting upon the base plate, a guide plateprovided with a longitudinal recess to receive said flanges, a rack barhaving an outward extending lug slidably mounted in the upper end of theslot, said rack bar having a longitudinal recess extending inward fromone end, a stud arranged in the recess, a cutting member having flangesformed upon its longitudinal. edges and disposed in said recess, saidcutting blade having an opening to receive said stud, and manuallyoperating means adapted to engage the rack bar to reciprocate the secondcutting member.

2. In a device of the character described, the combination of a baseplate, said base plate being provided with a longitudinal opening havinga central enlargement, a cutting member arranged in one end of the slotand extending outwardly beyond the face of the base plate, flangesformed upon the longitudinal edges of the cutting member and engagingthe inner face of the base plate, a guide plate having a longitudinalrecess to receive said flanges, a rack bar, an outward extending lugformed on said rack bar and slidably mounted in the upper end of theslot, said rack bar having a longitudinal recess extending inward fromone end thereof, a stud arranged in said recess at the inner endthereof, a second cutting member, having flanges formed upon itslongitudinal edges and arranged within said recess, said cutting memberhaving an opening formed therein to receive the stud in the recess, saidcutting member being slidably mounted in the slot and extendingoutwardly beyond the outer face of the base plate, cutting edges formedupon the opposed ends of the cutting members, and manually operatingmeans engaging with the rack bar to reciprocate the second cuttingmember.

In t-estlmony whereof I hereunto affix my slgnature 1n the presence oftwo wltnesses.

PHILIP NELSON.
